The Vatican and Colosseum full-day tour puts Rome's two biggest sights into one guided day, so you do not have to work out tickets, timings and the trip across the city on your own. Groups are capped at 10 people, the tour runs in English and everyone gets a wireless headset, which helps a lot in the crowded halls of both sites.

The day starts at the Colosseum. You meet at Colle Oppio Park, a short walk from the amphitheatre, and a guide takes you through the arena where gladiators once fought, with the Roman Forum and Palatine Hill spread out beside it. Reading up on the history of the Colosseum before you go makes the stories land better.

Around midday you get free time for lunch at your own expense, then the group continues to the Vatican side of Rome. A second guide leads you through the Vatican Museums to the Sistine Chapel and Michelangelo's ceiling, and the visit takes in St. Peter's Square. The listing notes that if the Sistine Chapel closes for reasons outside the operator's control, there is no partial refund.

Bring a passport or ID card on the day, it is required. If you would rather plan the two visits yourself, our guide to Vatican and Colosseum tickets walks through that route.
